Con đường đất có độ dốc khá cao.

Definition

1. Noun:
   • Slope / Gradient: The measure of how steep a surface is, such as a hill, road, or roof. It describes the rate at which the surface rises or falls relative to the horizontal.
   • Incline / Grade: The degree of this steepness, often expressed as a ratio, percentage, or angle.

Usage Examples

• Noun:
  • Độ dốc của con đường này rất nguy hiểm. (The slope of this road is very dangerous.)
  • Kỹ sư tính toán độ dốc tối đa cho tuyến đường sắt. (The engineer calculated the maximum gradient for the railway line.)
  • Mái nhà có độ dốc vừa phải để thoát nước. (The roof has a moderate incline for water drainage.)

Advanced Usage

• "độ dốc đứng" / "dốc đứng": A very steep or vertical slope, a cliff.

  • Vách đá có độ dốc đứng. (The cliff face has a vertical slope.)

• "độ dốc thoải": A gentle, gradual slope.

• Độ nghiêng (n): Angle of inclination, tilt. Often used for objects or surfaces that are leaning, not necessarily a continuous ground surface.

  • Độ nghiêng của tháp. (The tilt of the tower.)

Synonyms

• Slope: The general term for an inclined surface.
• Gradient: A more technical term, especially in engineering and mathematics, for the steepness of a line or surface.
• Incline: A surface that slopes.
• Grade: Often used for roads or railways (e.g., a 6% grade).

• Phần trăm độ dốc: Percent grade (e.g., a 10% slope rises 10 units for every 100 horizontal units).
• Góc dốc: Slope angle (measured in degrees).
